[A pure girl's heart, armpits, and pheromones floating in the air...] Emma, ​​my childhood friend who has a boyfriend, showed me her armpits. Apparently she wants me to do a final check before the date. She was reluctant, but as she reluctantly observed, Emma seemed embarrassed. She felt like she was looking at something erotic that she shouldn't see, and I couldn't contain my excitement either. The distance between them makes them inexplicably attracted to each other, the heat and scent of their armpits fragrant. In this fetish world, the two of them have opened the door to a new sexual fetish.
